Using Cloud-init Scripts¶

When ordering a new server or reinstalling an operating system, you can use Cloud-init scripts for automatic server configuration. This feature allows you to automate initial system setup immediately after OS installation.

The Cloud init script field is located in the Advanced options section when:

Ordering a new server;
Reinstalling the operating system.

Attention

The field appears only after selecting an operating system.

Script Format¶

The Cloud-init script must be written in YAML format, adhering to the following requirements:

Strict indentation (use spaces, not tabs);
Start with the directive #cloud-config;
Follow YAML syntaxю

Example Script¶

#cloud-config
users:
  - name: demo
    ssh-authorized-keys:
      - ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQCv60WjxoM39LgPDbiW7ne3gu18q0NIVv0RE6rDLNal1quXZ3nqAlANpl5qmhDQ+GS/sOtygSG4/9aiOA4vXO54k1mHWL2irjuB9XbXr00+44vSd2q/vtXdGXhdSMTf4/XK17fjKSG/9y3yD6nml6q9XgQxx9Vf/IkaKdlK0hbC1ds0+8h83PTb9dF3L7hf3Ch/ghvj5++tWJFdFeG+VI7EDuKNA4zL8C5FdYYWFA88YAmM8ndjA5qCjZXIIeZvZ/z9Kpy6DL0QZ8T3NsxRKapEU3nyiIuEAmn8fbnosWcsovw0IS1Hz6HsjYo4bu/gA82LWt3sdRUBZ/7ZsVD3ELip [email protected]

How to Use¶

Select the operating system;
Expand the Advanced options section;
Insert your YAML script in the Cloud init script field;
Ensure proper indentation and syntax;
Continue with the ordering or reinstallation process.

Attention

It is critically important to maintain correct indentation in YAML format! Without proper indentation, the script will not work correctly.
